Detail Information

Filtering with Silica Mesh Casting Filteris an effective way to remove inclusions and slag from steel, copper-based metal alloys, aluminium, gray, malleable, white, compacted graphite and ductile cast iron. Able to withstand pouring temperatures up to 1,650 C.deg (3,000 F), filter shapes help trap inclusions and reduce turbulence during the casting process. On contact with molten metal, the surface fibers of the filter form a sticky layer of fayalite. This allows the mesh filter to remove even micron-sized inclusions from the beginning of the pour to the end.

Silica Mesh Filtration is an economical solution at extracting dross,slag, refractory particles and nonmetallic inclusions,make the waste product of casting reduce by 50~60%.

*Best Results with Hot Topping – the filter can easily be removed after the pour so that there is no metal flow restriction during the exothermic action of the Hot Topping.

*No custom pour cone required – foundries using ceramic foam or cellular filters typically have to use custom-made pour cones that have a small ledge added to the inner wall of the bottom for the filter to sit on.

*Can sit on the top of any standard pour cone.

*No pre-heat required –unlike ceramic foam or cellular filters, silica mesh filters can be placed in the pouring cone just prior to the pour.

Specifications:
